What this means is that your ECU is pulling ignition timing because you're experiencing knock. What type of fuel are you running?
Here is something to side-by-side compare with your car. Keep in mind that this is a nearly finalized tune though, or at least close to what I'd consider ideal for my needs.

Edit: Did Open Flash make you get a new MAP sensor? IIRC Moto-East and Delicious recommend MAF tunes and default MAP sensor because of inadequate pressure readings. Not sure how much experience openFlash has with this kit. |
I saw the low IAM so it definitely needs timing removed. CA 91 gas is pretty bad and that's with me running Chevron. But before the timing is adjusted I want to make sure the code is taken care of.
It was running rich so my fuel trims were like -20% LTFT. I scaled the MAF but even after scaling the MAF the fuel trim vary a lot when I apply the throttle. During coasting the fuel trims and AFR are good but as son as start lifting off the throttle the STFTs go high positive. So only think I can think of is that the varying fuel trims are what are triggering the code.
I believe the tune is MAF based as I have the stock MAP which only reads up to 5 psi or so and Open Flash knows it the stock MAP. As you apply throttle and remove your foot off the throttle and decelerate do your STFTs vary a lot and go high positive?
